The Hangzhou Police has arrested ex-Taobao manager, Yan Limin, as part of ongoing investigations on suspicion of bribery, says Taobao's parent company Alibaba Group.

Alibaba's human resource department made the announcement Thursday in an open letter republished by various Chinese news sites. Yan, who oversaw Taobao's daily deals site Juhuasuan, was fired in March for "serious misconduct" over the management of his team, said the company.

It revealed that since the sacking, Alibaba's Integrity and Compliance Office and the Hangzhou police had conducted an investigation to determine if the former employee accepted bribes during his stint at Alibaba. No action was taken until now, it added.

Alibaba was hit with corruption scandal in February when internal investigations found a rise in fraudulent activities. Two senior executives who were not involved in such activities resigned following the investigations.
